Application filed June 13, 191%. Serial No. 239,760.

To all whom it may concern:

" Be it known that 1, JOHN B. HADAWAY, a citizen of the United States,residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented certain Improvements in Lasting-Machines,of which the followingdescription, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for use in lasting shoes and moreparticularly to machines for lasting shoes in which the upper is securedto the bottom ortion of the shoe in the lasting operation by the use ofcement as, for example, in the manufacture of fabric shoes which are tohave rubber outsoles vulcanized to them.

In the manufacture of shoes having vulcanized soles, the innersole, inaccordance with the usual practice, is formed of a rubber compound knowngenerally as rag stock. This innersole is relatively thin and pliableand its outer surface is rendered tacky by the application of a suitablerub-- ber compound. The upper of the shoe, when prepared for lasting,has the inner face of its margin coated with rubber cement which, whenbrought in contact with the tacky surface of the innersole, adheresfirmly thereto. Heretofore, shoes of this kind have been last ed almostentirely by hand, the upper being merely bent over the edge'of the lastagainst the innersole by a rocking or wiping motion of the hand,particularly of the thumb. This hand work is exceedingly laborious and,by reason of the consequent fatigue of the operator and the generalunreliability of the hand operation, uniform results in the course of a.days work are difficult to obtain. As a consequence, the manufacturerfinds in his product a large number of reject shoes which have to bedisposed of, if at all, at a greatly reduced profit or at a loss.Furthermore, it is practically impossible for an operator to apply withhis fingers any substantial tension to the upper to shape it to thecontour of the last since the effort required for the mere working overof the upper properly upon the innersole taxes the endurance of a personof ordinary strength when kept up continuously in the days work. Anobject of this invention is to provide a machine for doing the work morerapidly than it can be done by hand and for performing the stretchingand overlaying of the upper more reliably and effectually than ispossible by human agency alone.

A feature of the invention consists in an organization including wipingmeans for overlaying the margin of a shoe upper upon the bottom of thesole, which means has continuous pressing engagement with the overlaidupper margin throughout its width, and means for moving the wiping meanscontinuously in a direction inwardly of and over the shoe bottom. Asshown herein, the continuously pressing or wiping means may be offabric.

Another feature of the invention consists in an organization includingcontinuously effective overwiping means and means which may also becontinuously effective for upwiping the upper at the side of the shoe.As shown herein, the machine is organized for lasting the shoeprogressively and the continuously effective upwip-ing means is arrangedto act in advance of and also simul taneously with the continuouslyeffective overwiping means. In the construction shown, two belts ofsimilar construction are provided, one constituting the upwip-ing means,and the other the overwiping means. The upwiping belt is arranged inadvance of and offset from the overwiping belt so that after a portionof the upper is wiped upwardly against the side of the last, the marginof that portion is immediately thereafter engaged by the overwip-ingbelt and laid against the bottom of the shoe. The belts are preferablyarranged to be actuated positively and at the same speed.

An upper can be more effectively worked over a last by a varying orpulsating force than by a continuous pull or drag of sustainedintensityf Accordingly a feature of the invention consists in means forimparting a varying or pulsating quality to the action of the Wipingmeans during the opera tion of working the upper into lasted position.This result may be obtained, as in the construction shown, by wipingmeans which consists of a continuously moving means,

for example, a belt upon which are arranged protuberances whichsuccessively engage the upper and impart the pulsating effect to the.action of the belt in the conformation of the upper to the last.Between the protuberanc'es or projections the belt itself acts uponPatented Dec. 2th, 1921i. 7

' the upper and the upper is therefore treated,

alternately by a projection and by the intervening section of the belt.

- Preferably the belt or wiping means has rigid and yielding portionswhich act in turn upon the upper to treat the upper with varying degreesof intensity, for example, successively to hard and light wipingactions. As herein shown, the wipin means comprises a continuouslydriven %)elt of yielding material which is provided on its acting facewith hard protuberances which treat the upper to successive hard wipingacpulley is arranged at the side of the shoe 1 to support the lowerportion of the upwiping belt and another pulley is located over themargin of the shoe bottom to hold the overwiping belt in engagement withthe upper. These pulleys are preferably grooved to accommodate theprotuberances upon the belts and are provided with means shown asflanges to prevent relative dis placement of the belts and pulleys dueto the. drag of the shoe upon the belts as it is fed in eitherdirection. It will be observed that by this organization either beltconstltutes a rest or work positioning means for locating the work withrelation to the other belt, the pulley at the side of the shoesupporting the belt for location of the work with relation to theoverwiping belt and the, pulley located over the margin of the bottom ofthe shoe supporting the overwiping belt for location of the shoerelatively to the upwiping belt. Preferably, however, alshoe rest-isprovided in addition to the "pulley and belt over the margin of the shoebottom for positioning the shoe in proper relation to the wiping meansand the rest may, as shown, he yieldingly mounted to allow varyingintensities of overwipmg effect to besecured by variation of thepressure with which the shoe is upheld aga nst the rest and henceagainst the overw1 lng means.

nother feature of the invention con sists in means forrelativelydisposing the operating portion of the upwiping belt which is leavingthe pulley at the side of the shoe and the operating portion of theoverwiping belt which is approaching the pulley over the bottom of theshoe at an angle which approximates the angle between the side of thelast and the bottom of the justably to the machine frame.

last so that the operating portions of the upwiping beltwill be held in"engagement with the last at the side of the shoe adjacent to the bottomand the operating portions of the overwiping belt will engage the upperthroughout the width of the overwiped margin of the upper. Preferablythe pulleys are arranged for vertical and lateral adjustmentto enablethe angle between the said portions to be varied. This provision foradjustment of the pulleys also enables the field of action of the beltsvertically at the side of the shoe and laterally over the shoe bottom tobe varied and also enables the area of the upper treated by the sidewiping belt and the area treated by the overwiping. belt to be increasedor diminished. As herein shown, the operating portions of the belts arecarried over idlers which are arranged for adjustment to maintain thebelts tight when adjustments of the pulleys-adjacent to time operatingportions of the belts are mwc.

These" and other features of the invention will appear more fully fromthe following detailed description when read in connection with theaccompanying drawing, and will be pointed'out in the appended claims.

In the drawing 1 'iFigure 1 iso. side view of the machine showing theshoe in section, and

i Fig. 2 is a perspective view showing the operative parts of themachine in their relatipn to a shoe being operated upon.

Referring to Fig. 1 of the drawing, the numeral 2 indicates the frame ofthe machine in which is journaled a shaft 4 having a pulley t to whichpower is applied Fixed to the shaft 4 isa wide driving pulley '8 uponwhich are arranged'two separate belts 10 and 12. The belt 10 passes fromthe pulley 8 downwardly to an idler 14 mounted on a bracket 16. Thebracket is slotted at 18 and is secured to the frame by a bolt 20 whichpasses through the slot 18 and through a slot 22 inthe frame. By means,of the bolt 20 and slots 18 and 22, the bracket 16 may be adjusted totighten the belt 10. From the idler 14 the belt 10 passes to a pulley 24located opposite the side of the shoe. The pulley 24 is mounted on abracket 26 slotted at 28 and held to the frame 2 by a bolt 30. From thepulley 24, the belt passes I to a wide idler 32 and thence back to thedriving pulley 8. The belt 10, as it' passes up over the pulley 24, actsagainst the upper at the side of the shoe to wipe it toward the shoebottom. 7

The belt 12 passes from the driving pulley 8 to a pulley 34 located overthe shoe bottom and adjacent to its edge. The pulley 34 is mounted on abracket 36 having a slot 38 through which the bolt 30 passes and holdsthe bracket 36 as well as the bracket 26 ad- From the pulley 34 the belt12 passes to an idler 40 adjustably held by its pivot bolt 42 in a slot44 formed in an overhanging portion of the frame 2. Thence the belt 12passes over the wide idler 32 back to the driving pulley 8 by the sideof the belt 10. The pulleys 24 and 34 are provided with flanges, asshown, to prevent lateral movement of the belts in response to the dragof the upper as it is moved past the belts during the lasting operation.I a

:Fixed to the frame 2 above the shoe is a guide 50 in which is a slidingblock 52 having a lug 54 which extends through a slot 56 in the guide50. A compression spring 58 between the bottom of the guide and thesliding block 52 normally holds the lug 54 against the lower end of theslot 56. A cap screw 60 is threaded into the lug 54 and is embraced byan open slot 62 in a shoe rest member 64. This member may be adjustedvertically or laterally of the shoe and held rigidly to the lug 54 bytightening the screw 60. The member 64, however, may yield verticallyagainst the spring 58. The lower end of the member 64 is formed, asshown, to engage the bottom or sole of the shoe locally at a pointsubstantially beneath the axis of the pulley 34. The member 64 is cutaway on its inner edge .to avoid the possibility of its interfering withthe overlaying of the upper margin against the shoe bottom.

The belts are preferably composed of textile material and may, as shownherein, be made of a plurality of strands of cord arranged side by side.While the use of fabric or cord belts alone is contemplated, it isperhaps preferable to employ belts which are provided at short intervalswith protuberances, for example, metallic bands or clips 68. These clipsare firmly fixed to the belts by being compressed into the material ofthe belts and are arranged at regular intervals. Toaccommodate theclips, the driving pulley and preferably all the pulleys, are providedwith grooves which the clips engage as they pass over the pulleys. Theclips and grooves provide, of course, means for actuating the beltspositively from the driving pulley without slippage.

The pulleys 24 and 34 may, by loosening the bolt 30, be adjusted to varythe angle between the operative portions of the belts 10 and 12, forexample, to cause the angle between them to approximate the anglebetween the side and bottom of the last. The

pulleys 24 and 34 may also be adjusted to vary the length of theoperative portions of the belts, that is, the length of the. belt 10from the pulley 24 to the point where it crosses the other belt or thelength of the belt 12 from the point of crossing to the pulley 34. Inthis way the length of the wi ing operation of either or both belts maybe varied. The slots 22 and 44 enable the slack of the belts to be takenup whatever the adj usted position of the rolls 24 and 34 may be.

In the operation of the machine, a shoe prepared for lasting is heldagainst the rest 64 with its side against the belt 10 which acts to wipeand draw the upper upwardly at the side of the shoe toward the lastbottom. The shoe is now pressed upwardly, the rest 64 yielding to allowthe belt 12 to come into wiping contact with the upwardly extendingmargin of the upper and wipe it into contact with the margin of theinnersole where it is held by the cemented surfaces. The shoe is thenmoved transverselyof the belts lto cause successive port-ions of theupperto be treated first to an upwiping action by the belt 10 and thento an overwiping action by the belt 12. 'When these operations have beenperformed about the periphery of the shoe, it is ready for theapplication of an outsole.
